6 Disc Cd Player

Just wanted to know what the small black square plug on the back of the cd player is used for. The big plug plugs into the wiring harness on the truck. Thanks so much. HOTROD2987

I believe that is for the satellite radio to plug into

Sorry about the lack of info . I installed a 6Disc cd player in my 03 silverado everything works great but I did not know what the other plug was for . I thought it might be a plug for a AMP thanks for the info.HOTROD2987
